Explanation

Let total income be = x
 after spending 20% of x he has = 10080​x

after spending 70% of remaining he has
=10030​×10080​x
10030​×10080​x=1800
x=241800×100​=300×25=7500

Explanation

At 5% loss. SP =Rs.95x100$=Rs.\frac{95x}{100}$

Now,95x100+80=105x100$Now,\frac{95x}{100}+80=\frac{105x}{100}$

=>105x100−95x100=80$=>\frac{105x}{100}-\frac{95x}{100}=80$

=>105x−95x100=80$=>\frac{105x-95x}{100}=80$

=>x=800010=Rs.800
